WDCB, one of two stations in the Chicago area that continue to broadcast jazz, is airing three Night Lights programs in a row on Labor Day Monday evening, from 7 to 10 p.m. Central Time-Cats Who Swing and Sing: Women Singer-Pianists of the 1940s and 50s, 1959: Jazz's Vintage Year, and Porgy and Bess: the 1950s Jazz Revival. KUNV-Las Vegas will also broadcast The Horace Silver Songbook at 10 a.m. Pacific Time Monday morning, on the eve of Silver's 80th birthday. (KMHD-Portland, Oregon, which carries Night Lights weekly, will air the Silver program in its regular Monday 8 p.m. PT timeslot.) As always, this weekend's show will be available by Monday for online listening as well. Happy Labor Day... with hopes for a cool autumn ahead.
